This is usually because fstat(2) fails on file descriptors that have been
revoked. By the time that message is printed, the /dev/console descriptors
that were inherited from /etc/rc etc would have been revoke(2)'ed by the getty
on /dev/ttyv0 or ttyd0.
cron also used to do this. It would end up with handles to the console
that would get revoked, and sendmail would get upset when cron fired it up.
I "fixed" that a while back in cron to ensure that it had valid handles.
Have a look at lsof/fstat output for the revoked fd's, and you'll probably
find some new ones now.
Cheers,
-Peter
